[0038] In the embodiment, the suction air duct 110, the suction opening 111 and the middle suction passage 230 are arranged in the front-rear direction, so that the range of the suction coverage is wider.

[0039] In the embodiment, in the closed position, a gap is left between the circumferential side of the flap structure 200 and the base 100 to form the circumferential suction passage 400, so that the suction of the powder spraying can be performed around the left flap 210 and the right flap 220.

[0040] In the embodiment, one side of the left flap 210 is provided with a left default slot 211, and one side of the right flap 220 is provided with a right default slot 221; in the closed position, the slot openings of the left default slot 211 and the right default slot 221 are butted against each other, and the slot walls of the left default slot 211 and the right default slot 221 enclose to form the middle suction passage 230.

[0041] In the embodiment, in the closed position, the corresponding sides of the left flap 210 and the right flap 220 are butted against each other. The butting manner makes the corresponding sides of the left flap 210 and the right flap 220 form a fit, the flap structure 200 formed by the splicing of the left flap 210 and the right flap 220 is more stable, and the butting fit does not affect the quick splitting and fitting of the left flap 210 and the right flap 220.

[0042] In the embodiment, the front-rear sides of the left default slot 211 are respectively provided with a left front slot shoulder 212 and a left rear slot shoulder 213, and the front-rear sides of the right default slot 221 are respectively provided with a right front slot shoulder 222 and a right rear slot shoulder 223; in the closed position, the left front slot shoulder 212 is butted against the right front slot shoulder 222, and the left rear slot shoulder 213 is butted against the right rear slot shoulder 223. The above butting fit structure is symmetrical in structure and more stable in fit.

[0043] Reference Figure 5In the embodiment, the left flap 210 and the right flap 220 are provided with inclined surfaces on the corresponding sides, and the left flap 210 and the right flap 220 are matched with each other through the inclined surfaces.
